POPULATION EXPLOSION

POPULATION EXPLOSIONIt refers to the structure of the population.It helps us to know how many males or females ,which are the group do they belong ,how educated are they and what work they do, what are their earnings and health conditions.More population doesn’t mean higher economic development e.g. both Bangladesh and Japan are Asian countries and they are densely populated but Japan is far more economically developed than Bangladesh . Education and health play crucial role in the development of humans as resources.We can study the population composition by making a population pyramid.It shows :

1.total population divided in to various age groups ,e.g. 5 to 9 years 10 to 14 years .

2. the percentage of the population subdivided into males and females in each group.

The shape of the population tells us about the people living in the country. The number of the children below 15 years are shown at the bottom and indicates about the level of births.

POPULATION PYRAMID

The size of the top shows the number of aged people [about 65 years ] and tells the number of deaths .The population pyramid also tells us about the dependent population. There are two groups of dependents- young dependents[aged below 15 years ] and elderly dependents [aged over 65 years].Those of working age between 15 and 64 are the working population.
